Ditto. Shellac is not a good choice for outdoor wood furniture. (Sorry, I know it's too late.)

I dont know anything about advanced aquarium pumps.
But have you considered using a UPS battery backup?

When the power goes out, it will automatically move to battery power and will continue to run your pumps uninterrupted.
Its like unplugging a laptop from the wall.

In the ~$100 range you can find ones built for high powered desktop computers.

The power draw from your pumps will be a fraction of what a gaming pc is, so it would run the pumps for a long time.

I have an ultra small form factor PC running a fileserver. I have it on a 825VA UPS backup.
The calculations say that at idle my mini pc and raid array would run up to something stupid like 27 days straight on just battery power.

You could easily find something that would give you days worth of power for cheap.

Your questions indicate that you lack sufficient knowledge to handle a high powered laser safely. Stick to 1mW ones

Also don't expect chink shit lasers to get anywhere near their specs

You are going to blind yourself or someone else
Its not a joke, and even if you did somehow slap this thing together youll get bored of it in 20 minutes.

I may be biased as im a metalworker but it looks simple enough that could make one out of brass yourself with a vise, a jewelers saw, some files and a hammer. What are the rollers usually made of?

>>1101993
I have no clue, to be honest. Looks like carbon steel? Perhaps copper even. But I'm interested in your method. I have a friend who is an excellent metalworker as well, care to share?

>>1101988
They work like a penstriper.

The center is hollow with a lid that you put liquid ink in ( like think fountain pen ink)
The edge that is need the rollers have either a small slot cut into them or a small hole drikker into them so that the knurled section of the roller can pick up ink.

In its most simple form it is a box, with tabs that are drilled to act like a bearing for a roller that hase some knurrled raised sections.

bout the only thing I could think of, chuck in a pump with a hydrocarbon water filter in line, take the water from that meantime, this shouldnt be that expensive or complicated to rig up. Otherwise? - wait till it rains a lot, which may not be a genial solution, but, its infinitely smarter than adding fucking degreaser to your water supply, IMO.

Throw a match in the well.

Anon... Was it your truck? Are you the fucker?

Oil spills
Another chronic problem in many rural homes is leaking or spilled fuel oil which eventually contaminates the owner's own well. Many homes have a fuel tank, either buried or above ground, adjacent to the house and within a few feet of the well. Spills or accumulated leakage eventually can migrate to the aquifer and can be drawn into the well, making it unusable for years. Usually the only solution is to obtain a new water source. In some instances, however, reducing the pumping rate to reduce drawdown allows the oil to float on the water surface safely above the well's intake area.

https://pubs.usgs.gov/gip/gw_ruralhomeowner/gw_ruralhomeowner_new.html

You could probably work out a pretty expensive filter system to make it usable in the house again. Hopefully you don't have to replace all your plastic shit. Hydrocarbons impregnate some plastics and will leach out for years.

Getting quotes on another well might be worth it. Or the well guy might have some other... Solutions.

maybe the neopixel product line from adafruit is what you need?

Thank you so much, anon! This is exactly the one I was looking for!

Maybe it's just me being used to the direct-from-China/bulk pricing, but all these "ready to go" modules I keep seeing seem so overpriced.

Seconding this, mite b cool.

There's always that guy that built a full working miniature internal combustion engine, that shit was fucking neat.

https://blackmesalabs.wordpress.com/2016/10/24/sump2-96-msps-logic-analyzer-for-22/ cheapest way of getting near 100MSPS, analog stuff might be easier on a different board

>Not getting the Analog discovery 2
ayy
My university had this deal going with Digilent where the discovery 2 was 75 dollars or something, plus free parts.
Shit is so cash, good luck in getting one.

>>1101810
you can buy any cheap chinese logic analyzer, (https://www.aliexpress.com/item//32328690865.html)
they're basically just an adc and fpga in a box; all the magic is in the software and luckily salea offers a free download of theirs https://www.saleae.com/downloads

if you don't want to buy a ripoff the DSLogic pro is also a good product and it comes with it's own software

these

Do you really need the original and can't use emulation?

>>1101614
Of course I could, but Its a whole another feeling listening to a "real" one (I know it doesnt sound different). Also its a nice demo hearing one of one of these working

>>1101612
>Where do you get them nowadays?

Get a C64 from eBay/garage sale/Goodwill and pull it.

Will I be able to do it on my own without dropping it?

Now this thing has an internal speaker. I opened it up and pic related is what I found. Unfortunately, this device does not have an external audio jack.

>>1101285
Get an op-amp and maybe a larger speaker. done.

So should I solder a jack to the speaker's connection points and run that to an amp like this?

Make it out of materials from harbor freight, they sell some of the best tools for realistic prices (other stores often raise the prices dramatically and false advertise their uses). You can make the base of the desk out of pallets as they are built to last and will not break under pressure.

Solid oak. It'll cost you but if built right will last forever

watch a lot of youtube videos, and make stuff yourself until you're good.

>I don't know which videos/books
any will do. If you've watched/read enough, you'll better understand which were shit and which weren't.

>what tools should I buy?
whichever you need. Buy cheap stuff until you have enough experience to see where you need quality and where you don't

>but what should I build?
Whatever you need. Alternatively, google "beginner woodworking projects"

Come back if you have specific questions to a project you already had some thoughts about and formulated a concrete plan.
Also, fyi, there's a stupid questions thread on /diy/ (if not, make one), where you can ask simple questions. I'm sure you'll be there a lot.

get ready to spend on tools, and spend on wood

Get:
1) Pencil
2) Straight edge
3) a) Rough and b) fine hand saw (e.g. fatmax or irwin) or flea market 2$ saws
Then go to the store and buy some 2x4s and 2x6s and build some outdoor furniture. You don't need many.
If you need plans or ideas this is where you search internets or go to the bookstore. Try some mortise and tenon joinery with screws and glue with aforementioned furniture.

IF you hate it up to here. Stop. You've probably invested maybe 15$ for the chisel set and another 30$ for the handsaws and whatever for the 2x's so give up now.
If you have power tools, fine but you're better off with hand tools for now anyway.

put a sign on it
make the cost ridiculously low

the description must say "I KNOW WHAT I GOT"

>>1100761
It's kinda low, just not super low. Sign won't help much since it's out of town limits and in a ranch, so I don't think a lot of people will see it.

>>1100763
short of spamming it online or spreading word to your friends' friends theres not much you can do
